Could not load helper Nightmare from module './helper/Nightmare'

What are you trying to achieve?

Hi @DavertMik , I’m trying to run tests with Nightmare (both nightmare and nightmare-upload have been installed globally):

codeceptjs run . --steps

What do you get instead?

Got following:

Could not load helper Nightmare from module './helper/Nightmare':
Required modules are not installed.

RUN: [sudo] npm install -g nightmare nightmare-upload
{}

Error:

My test code is:

Feature('Hellooworld');

Scenario('Login page loaded', (I) => {
  I.amOnPage('/');
  I.seeElement({name: 'password'});
});

Details

• CodeceptJS version:
• NodeJS Version:
• Operating System:
• Protractor || WebDriverIO || Nightmare version (if related)
• Configuration file:

{
  "tests": "./tests/e2e/*_test.js",
  "timeout": 20000,
  "output": "./tests/e2e/output",
  "helpers": {
    "Nightmare": {
      "url": "http://localhost:3000",
      "show": false 
    }
  },
  "include": {},
  "bootstrap": false,
  "mocha": {},
  "name": "ui"
}

Any thoughts about it? Thanks

Now as I expand my sample test to:

Feature('Retrieve booking');

Scenario('test something', (I) => {
	I.amOnPage('http://localhost:3000');
});

It errors with:

> codeceptjs run --steps --verbose

CodeceptJS v0.5.1

I met the same question after global installation. I solved the problem by changing to local installation and edited the codecept.json as followed ：

"node_modules": {
    "Nightmare": {
      "url": "",
      "show": false,
      "restart": false
    }},

It works for me.
